The Impact

Relevance. The current theory of specific bacterial biofilm fails explain why a part of patients experiences inflammatory periodontal diseases while the absence of detected specific types of “red complex” bacteria.Purpose. To clarify the microbiological and immunological mechanisms of the influence of the viral and bacterial consortium in the etiology and pathogenesis of inflammatory periodontal diseases.Materials and methods. Articles survey with elements of metanalisis. Literature review based on discussion of research results on the topic of 48 sources including 33 foreign ones.Results. The review provides evidences of the possible participation of viruses of the Herpesviridae family in the development of chronic generalized periodontitis. Evidences for the role of herpes simplex viruses of type 1.2, Epstein-Barr virus, and cytomegalovirus in the development of periodontal inflammation are analyzed. It is proven that all herpesviruses induce the release of proinflammatory cytokines that activate osteoclasts and matrix metalloproteinases, as well as violate antibacterial immune mechanisms. In turn that leads to a progressive increase of periodontal pathogenic bacteria in both the biofilm and periodontal tissues.Conclusion. It is made a conclusion that an active herpetic infection can initiate damage to periodontal tissus and participate in the development of relapses of the disease.

Tlr Signalling

Gingivitis and periodontitis are induced by numerous pathogenic microbiota hosted in the subgingival biofilm that first trigger the innate immune response. Innate immune response is part of a homeostatic system which is the first line defence and defines the host inherited resistance to infection. Both genetic and environmental factors are involved in variable individual susceptibility to inflammation of periodontal tissues. That is why, although more than 600 bacterial species have been detected in the periodontal plaque, the type of bacteria incriminated in the development of the inflammation is still unclear. Moreover, in the last decade gene polymorphisms have been largely recognised as important conditions associated with increased susceptibility to periodontal diseases. Manipulating the immune response by the development of drugs that inhibit adverse host reactions and promote beneficial effects might be of therapeutic or prophylactic importance. This work intends to assess the importance of Toll-like receptors as main effectors of the innate immune response in the triggering, maintenance and progression of periodontal inflammation, as well as of the involvement of synthetic molecules targeting TLR signalling pathways in treating periodontal diseases.

Subject. Despite the constant efforts of practicing physicians and scientists, the prevalence proportion of inflammatory and destructive periodontal diseases in the world is not subsiding. Previously scientists have examined several different theories on the development of pathological conditions in periodontal tissues, ranging problems from the neurotrophic theory of occurrence to the effect of occlusion injury on periodontal tissues. Theories dealing with the influence of specific and non-specific bacterial plaque have also been studied. None of the theories has become reasonable and single valued. It is believed that the mechanism of the development of the disease is complex, autoimmune, damaging primarily collagen, elastic fibers of the capillary endothelium, gingival ligament and bone tissue. Over the past decade, it has been proven that inflammation in periodontal tissues is initiated and proceeds in response to the introduction of pathogenic bacteria. However, it can be said that not all patients develop an inflammatory response to bacterial invasion. The second important factor in the development and progression of the inflammatory-destructive process is the immune response of a particular individual. Scientists have noted the influence of the non-microbial factor and have come to the conclusion that in the surrounding tissues of the inflamed area there are not only enzymes secreted by bacteria, but also leukocyte proteinases, which in turn are mediators of the tissue destruction. Purpose ― to examine the role of leukocyte proteinases in the pathogenesis of inflammatory periodontal diseases. Methodology. The number of indigenous and foreign literature sources dealing with the study of the role of leukocyte proteinases in the development and maintenance of a destructive inflammatory process has been reviewed by us. Conclusion. The role of the aggressive destructive effect of leukocyte proteinases on periodontal tissues has been analyzed. Leukocyte proteinases are mediators of progressive destruction of connective tissue and can be used as markers to assess the severity of the course and predict the development of the inflammatory process in periodontal tissues.

Periodontal diseases are one of the most significant challenges in dental health. It is estimated that only a few percent of the worldwide population have entirely healthy teeth, and according to WHO, oral diseases may affect up to 3.5 billion people worldwide. One of the most serious oral diseases is periodontitis, an inflammatory disease affecting periodontal tissues, caused by pathogenic bacteria and environmental factors such as the ageing population, abuse of tobacco products, and lack of adequate oral hygiene due low public awareness. Plant materials are widely and successfully used in the management of many conditions, including periodontitis. Plant materials for periodontitis exhibit antibacterial, anti-inflammatory, antioxidant activities and affect the periodontium structure. Numerous studies demonstrate the advantages of phytotherapy for periodontitis relief and indicate the usefulness of Baikal skullcap root, Pomegranate fruit peel and root cortex, Tea leaves, Chamomile flowers, Magnolia bark, Blackberry leaves and fruits, Cranberry fruits and Lippia sidoides essential oil. This review aims to analyze the use and applicability of selected plant materials in periodontitis management since it is of paramount importance to evaluate the evidence of the traditionally used plant materials in light of continuously growing interest in phytotherapy and its adjuvant role in the treatment of periodontitis.

Probiotics have aroused great interest as an adjunctive treatment to periodontal therapy, due to the frequent colonisation by periodontopathogens after therapy. The aim of this systematic review was to analyse in the scientific literature, evidence of the microbiological effects of probiotics as an adjunct to periodontal therapy in the treatment of periodontal diseases (PD). Only randomised controlled trials (RCT), evaluating the microbiological effect of probiotics as an adjunct to periodontal therapy. The authors conducted a search in PubMed/MEDLINE, LILACS, ScienceDirect, Web of Science and Cochrane Library to identify articles published in English until February 2020. The quality of the studies was assessed using the JADAD scale and the risk of bias was assessed according to the Cochrane Collaboration assessment tool. Of the 265 articles potentially relevant to this review, 10 studies were included. The most frequently used probiotic bacteria were those of the genus Lactobacillus spp. and the time of administration of the probiotics was between 14 days to 3 months. Most studies have shown that the adjuvant use of probiotics reduces the total mean counts of gram-negative anaerobic species (Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola and Prevotella intermedia) and gram-negative coccobacillus (Aggregatibacter actinomycetemcomitans) of subgingival plaque samples. Probiotics adjuvant to periodontal therapy reduces periodontopathogenic species in a greater proportion, compared only to periodontal therapy. Especially the Lactobacillus reuteri strain, without combination with other strains, offered a greater reduction in pathogenic bacteria associated with greater destruction of periodontal tissues and deep periodontal pockets. Researchers should perform high-quality RCT, evaluating single strains without combinations, in order to observe the microbiological benefits as adjunctive treatment of PD.

Main Thing

Subject. The prevalence of inflammatory periodontal diseases among elderly people, regardless of their gender, ranges from 69 to 98 % worldwide. Periodontitis is a chronic bacterial disease that proceeds with intoxication of the body, thereby causing serious health problems. It has been proven that periodontitis can cause myocardial infarction and habitual miscarriage. Local and systemic treatment of diseases of this pathology is primarily aimed at suppressing pathogenic bacteria. It is obvious that, in the conditions of total antibiotic resistance of microorganisms and a considerable list of contraindications and complications of the antibiotic therapy, the search for new ways to combat them becomes vital. The main thing is that antibiotics disrupt the biological balance of the biopsy of the body which the patient has to restore from several months to several years. Under these conditions, the use of bacteriophages is an extremely promising solution. Bacteriophages are natural antimicrobial highly sensitive medications. They consist of viruses that target a bacterial cell. In these circumstances, bacteriophages do not harm the microbiota of the oral cavity. A literature review on the use of bacteriophages in dentistry for the treatment of inflammatory diseases of periodontal tissues has been conducted by us. The mechanism of action of bacteriophages, the strengths and weaknesses of the use of phage therapy have also been considered. Goal ― to study the use of bacteriophages for the treatment of patients with inflammatory periodontal diseases. Methodology. The literature review of more than 40 scientific sources has been conducted. Conclusion. The use of bacteriophages is a promising issue. Their effectiveness has been confirmed in the treatment of infectious and inflammatory periodontal diseases and diseases of the oral mucosa. They demonstrate high efficiency to improve the hygiene of the oral cavity and reduce inflammation. Being highly targeted viral medications, they act upon a specific bacterium without affecting the natural microbiota of a person.

Abstract Background All soft and solid surface structures in the oral cavity are covered by the acquired pellicle followed by bacterial colonization. This applies for natural structures as well as for restorative or prosthetic materials; the adherent bacterial biofilm is associated among others with the development of caries, periodontal diseases, peri-implantitis, or denture-associated stomatitis. Accordingly, there is a considerable demand for novel materials and coatings that limit and modulate bacterial attachment and/or propagation of microorganisms. Objectives and findings The present paper depicts the current knowledge on the impact of different physicochemical surface characteristics on bioadsorption in the oral cavity. Furthermore, it was carved out which strategies were developed in dental research and general surface science to inhibit bacterial colonization and to delay biofilm formation by low-fouling or “easy-to-clean” surfaces. These include the modulation of physicochemical properties such as periodic topographies, roughness, surface free energy, or hardness. In recent years, a large emphasis was laid on micro- and nanostructured surfaces and on liquid repellent superhydrophic as well as superhydrophilic interfaces. Materials incorporating mobile or bound nanoparticles promoting bacteriostatic or bacteriotoxic properties were also used. Recently, chemically textured interfaces gained increasing interest and could represent promising solutions for innovative antibioadhesion interfaces. Due to the unique conditions in the oral cavity, mainly in vivo or in situ studies were considered in the review. Conclusion Despite many promising approaches for modulation of biofilm formation in the oral cavity, the ubiquitous phenomenon of bioadsorption and adhesion pellicle formation in the challenging oral milieu masks surface properties and therewith hampers low-fouling strategies. Clinical relevance Improved dental materials and surface coatings with easy-to-clean properties have the potential to improve oral health, but extensive and systematic research is required in this field to develop biocompatible and effective substances.

The diet is related to the diversity of bacteria in the oral cavity, and the less diverse microbiota of the oral cavity may favor the growth of pathogenic bacteria of all bacterial complexes. Literature data indicate that disturbances in the balance of the bacterial flora of the oral cavity seem to contribute to both oral diseases, including periodontitis, and systemic diseases. If left untreated, periodontitis can damage the gums and alveolar bones. Improper modern eating habits have an impact on the oral microbiome and the gut microbiome, which increase the risk of several chronic diseases, including inflammatory bowel disease, obesity, type 2 diabetes, cardiovascular disease and cancer. The subject of our consideration is the influence of the traditional diet on the formation of oxidative stress and inflammation caused by bacterial biofilm in the oral cavity. Through dental, biomedical and laboratory studies, we wanted to investigate the effect of individual nutrients contained in specific diets on the induction of oxidative stress inducing inflammation of the soft tissues in the oral cavity in the presence of residual supra- and subgingival biofilm. In our research we used different types of diets marked as W, T, B, F and noninvasively collected biological material in the form of bacterial inoculum from volunteers. The analyzed material was grown on complete and selective media against specific strains of all bacterial complexes. Additionally, the zones of growth inhibition were analyzed based on the disc diffusion method. The research was supplemented with dental and periodontological indicators. The research was supplemented by the application of molecular biology methods related to bacterial DNA isolation, PCR reactions and sequencing. Such selected methods constitute an ideal screening test for the analysis of oral bacterial microbiota. The obtained results suggest that certain types of diet can be an effective prophylaxis in the treatment of civilization diseases such as inflammation of the oral cavity along with periodontal tissues and gingival pockets.

Background: One of the methods of comprehensive therapeutic effects on the human body is sylvinite therapy which has not been used in the treatment of inflammatory periodontal diseases at young age. Aims: Hygienic and clinical evaluation of the possible application of therapeutic factors of sylvinite devices in dentistry.Materials and methods: We conducted hygienic study of the basic physical factors of the internal environment of modern sylvinite structures (radiation background, aeroionization and aerosol environment, climate). The percentage of sylvine and halite in the sylvinite minerals was determined using color image analysis of the salt screen. The microbiological studies of the impact of the mineral sylvinite on the growth parameters of bacterial culture were performed. We examined 79 patients aged 20−25 years diagnosed with chronic generalized catarrhal gingivitis, 36 persons underwent treatment course in the salt structure. The evaluation of the dental status and the periodontal status was conducted using hygienic and periodontal indices. The duration of study was 4 years.Results: Аll participants who entered the study completed it. In the experimental sylvinite room formed food-grade, biodegradable internal environment (background radiation ― 0,18±0,0027 µsv/h; LOA ― 802,33±62,69 ion/cm3; RO ― 509,33±37,17 ion/cm3; stable microclimate). We detected evidence of an inhibitory effect of the combination on Staphylococcus aureus. The use of a comprehensive dental program has improved the condition of periodontal tissues and careeradvantage tooth enamel (PMA and SBI fell of 80.8% and 75.5%; the reduction of the CPU ― 67.7%; fuel and energy resources increased by 37%). Conclusions: The inclusion of sylvinite therapy in the complex treatment of patients with chronic generalized catarrhal gingivitis had a marked positive impact on the state of periodontal tissues and local immunity of the oral cavity.

The purpose of this study was to identify the possibility of using a micronucleus test to assess the impact of harmful chemicals on the condition of periodontal tissues of employees of a mining and processing plant. Material and methods. Dental examination was conducted for 40 employees of the mining and processing plant, exposed to harmful substances with an experience of more than 10 years, 36 employees of the plant with a contact time of not more than 10 years, and 46 people with a healthy periodontium. The analysis of buccal epithelial cells for the presence of chromosomal aberrations using the micronucleus test. Results. The prevalence of inflammatory diseases of periodontal tissues in the groups of workers of the plant was 100%. A statistically significant difference was found in the frequency of cells with micronuclei and protrusions of the nucleus in the group of internship workers compared with other groups (p = 0.001). The frequency of cells with two nuclei in the workers of the plant in the groups was at the same level and significantly exceeded the value of the index for a group of people with a healthy periodontium (p = 0.002 and p = 0.006). The frequency of occurrence of cells with vacuolization of the nucleus in a group of workers with an experience of more than 10 years more than doubles that of a group of individuals with a healthy periodontium (p = 0.009). Conclusion. Occupational factors have a significant impact on the development and course of inflammatory periodontal diseases in mining and processing complex employees. Studies using the micronuclear test indicate a negative impact of a complex of harmful substances on the development and course of inflammatory periodontal diseases.

Periodontitis is characterized by deep periodontal pockets favoring the proliferation of anaerobic bacteria likePorphyromonas gingivalis(P. gingivalis), a periodontal pathogen frequently observed in patients suffering from periodontal inflammation. Therefore, the aim of the present study was to investigate the signaling pathways activated by lipopolysaccharide (LPS) ofP. gingivalis(LPS-PG) and hypoxia in periodontal ligament (PDL) cells. The relevant transcription factors nuclear factor-kappa B (NF-κB) and hypoxia inducible factor-1 (HIF-1) were determined. In addition, we analyzed the expression of interleukin- (IL-) 1β, matrix metalloproteinase-1 (MMP-1), and vascular endothelial growth factor (VEGF) in PDL cells on mRNA and protein level. This was accomplished by immunohistochemistry of healthy and inflamed periodontal tissues. We detected time-dependent additive effects of LPS-PG and hypoxia on NF-κB and HIF-1αactivation in PDL cells followed by an upregulation of IL-1β, MMP-1, and VEGF expression. Immunohistochemistry performed on tissue samples of gingivitis and periodontitis displayed an increase of NF-κB, HIF-1, and VEGF immunoreactivity in accordance with disease progression validating the importance of thein vitroresults. To conclude, the present study underlines the significance of NF-κB and HIF-1αand their target genes VEGF, IL-1β, and MMP-1 inP. gingivalisand hypoxia induced periodontal inflammatory processes.
